Telphusa Stoliczkana, n. sp. PL XII, Figs. 8 — 12. 



Carapace much broader than long, smooth, punctate, minutely 

 granular under a lens ; cervical suture distinctly marked mesially, 

 continued outwards and forwards on each side as a shallow depres- 

 sion which disappears posteriorly to the postfrontal crest, limiting 

 off the gastric area from the branchial lobes, the anterior halves of 

 which are distinguished from the posterior by their greater convexity ; 

 cardiac region perceptible ; antero-lateral margin carries a not very 

 salient epibranchial tooth, which is separated from the extra-orbital 

 angle by the oblique tuberculated external margin of the latter, and 

 passes backwards for a short distance as a tuberculated crest ; postero- 

 lateral margin covered with rugosities from which spring a few hairs ; 

 the inflected part of the carapace is more obscurely rugose ; the 

 posterior and anterior pleural lobes are smooth, the latter being 

 separated from the former, and from the inflected portion of the 

 carapace by a granulated line ; infra-orbital margins crenulate ; front 

 narrow, granulated ; its free margin is deeply bayed, having 

 in consequence a bilobed appearance ; postfrontal furrow smooth, 

 bounded poteriorly by a well defined crenulated crest which passes 

 from the mesogastric furrow to the epibranchial teeth in an un- 

 interruptedly straight line, that part of it which forms the 

 frontage of the epigastric lobes being rugose. 



The posterior margin of the epistoma is smoothly tubercular, 

 but those parts of it which go to form the boundaries of the efferent 

 apertures of the branchial chambers are entire. 



The chelipedes are greatly unequal in males and sub-equal in fe- 

 males ; the meropodites are rugose and have a few hairs near the 

 base of the posterior angle ; the carpopodites are rugose above and 

 bear a strong sharp spine in the usual position and beneath it a 

 smaller one ; the pincers are multidentate and their arms cross 

 at the extremities. 



The ambulatory legs are very long ; their meropodites resemble 

 those of Telphusa longipes, Alph. M.-Edwards, but their penultimate 

 joints are longer in proportion to their breadth and the last joints 

 are stouter and more elongated.
